Specification of Letters Patent.

Patented July 2, 1912.

Application filed March 29, 1912. Serial No. 687,061.

To all whom it may concern:

Be it known that I, JOHN B'ooosn, a subject of the King of Hungary,residing at McKeesport, in the county of Allegheny and State ofPennsylvania, have invented certain new and useful Improvements inWrenches, of which the following is a speci fication, reference beinghad therein to the accompanying drawing.

This invention relates to wrenches, and the primary object of myinvention is to provide a simple and inexpensive wrench that can be usedin places inaccessible to an ordinary monkey or spanner wrench.

A further object of this invention is to provide a strong and durablewrench consisting of parts easily and quickly assembled.

I attain the above objects by a mechanical construction that will behereinafter specifically described and then claimed, and reference willnow be had to the drawing, wherein:

Figure 1 is a front elevation of the wrench, Fig. 2 is a side elevationof a portion of the same, Fig. 3 is a front elevation of the wrenchpartly broken away and partly in section, and Fig. 1 is a perspectiveview of a portion of the wrench.

A wrench in accordance with this invention comprises handle sections 1provided with flat rectangular heads 2, said heads having theconfronting faces, at the outer ends thereof, recessed, as at 3. Thehandle sections 1 and the heads 2 are connected by rivets 4; or otherfastening means. The handle sections 1 and the heads 2 have theconfronting faces thereof longitudinally grooved to provide a bore 5 andsaid bore encircles a transverse opening 6 formed in the inner ends ofthe heads 2.

Pivotally mounted between the heads 2 and the recesses 3 by transversepins 7 are levers 8 that have the ends thereof bifurcated. The leversare curved and the inner ends are pivotally connected by pins 9 to theflat head 10 of a screw 11. The screw 11 is adjusted through the mediumof a nut 12 located in the opening 6, said nut having the upper andlower ends thereof rotatably held in the enlarged portions 13. of thebore 5.

The outer bifurcated ends of the levers 8 are pivotally connected bypins 14 to the inner reduced ends 15 of oppositely disposed jaws 16. Thereduced ends 15 of the jaws are pivotally connected by pins 17 to sidelinks 18 and said links are pivotally mounted in the recesses 8 by pins19 and spacing washers 20. v

The nut 12 is knurled and protrudes from the ends of the opening 6whereby it can be easily gripped by the fingers and rotated. By rotatingthe nut, the screw 11 is raised or lowered and when raised, the outerends of the levers 8 are swung outwardly, lowering the jaws 16, the jawsbeing supported in a vertical position by the side links 18. A veryminute adjustment of the nut 12 opens the jaws 16 to grip the facets ofa nut, and it is obvious that the wrench can be inserted in a socket orother small recess and a nut rotated therein.

What I claim is A wrench comprising a sectional handle, a head carriedthereby and having the outer end thereof provided with a recess, saidsectional handle having a longitudinal bore formed therein intersectinga transverse opening in the inner end of said head, levers pivotallymounted in the recess of said head, a screw located in the bore of saidhandle and having the end thereof pivotally connected to the inner endsof said levers, a nut rotatably supported within the opening of saidhead for adjusting said screw, jaws having reduced ends pivotallyconnected to the outer ends of said levers, and side links pivotallymounted in the recess of said head and pivotally connected to thereduced ends of said jaws.

In testimony whereof I affix my signature in the presence of twowitnesses.

JOHN BUGOSH.
